Lead Full-stack Developer — Chart of Accounts, General Ledger Core, Asset Lifecycle, and Budgetary Control.

2026
Built an end-to-end ERP ecosystem that centralizes disparate corporate financial operations into an audit-ready platform. The system features a hierarchical Chart of Accounts (COA) with Left/Right indexing (Nested Set Model) for recursive balance calculations, an automated fixed asset management module with multi-method depreciation, and an integrated budgetary enforcement layer. It replaces error-prone spreadsheet-based tracking with a strict, transactionally consistent double-entry engine.
A large-scale conglomerate was managing fragmented financial tracking and complex multi-currency data across five different subsidiaries using manual spreadsheets. This led to massive balance variance, delayed financial closings (12+ days), and a lack of real-time visibility into consolidated corporate cash flow and profitability.
How I engineered the system
Nested Set Financial Core: Implemented the Chart of Accounts using a Nested Set model (L/R indexing) in MySQL, enabling sub-millisecond recursive balance calculations across deep account hierarchies and multi-company consolidations without recursive SQL queries.
Automated Receivables & Payables Ledger: Orchestrated a robust transactional pipeline managing multi-currency accounts receivable/payable with automated invoicing, aging reports, and dynamic payment reconciliation trailing back to the General Ledger with 100% consistency.
Automated Asset Lifecycle Gear: Developed a professional-grade fixed asset module with multi-method depreciation (Straight-Line, Reducing Balance) that automatically generates monthly journal entries, ensuring audit compliance and truthful book values.
Proactive Budgetary Enforcement: Engineered a cost-center-scoped budgeting layer that validates every Material Request and Purchase Order against allocated funds in real-time, effectively preventing over-expenditure before the transaction occurs.
Audit-Ready Architecture: Built a state-driven document workflow (Draft → Submitted → Cancelled) with immutable ledger entries and a comprehensive audit log for every sensitive data mutation, making the system 100% compliant with external auditing standards.
What it accomplished in production
85% Reduction in Closing Time
Automated reconciliation and period-locking cut down month-end financial closing from 12 business days to just 36 hours through streamlined automated accruals.
50k+ Annual Cost Savings
Significant reduction in administrative overhead and audit-correction hours by automating financial operations, multi-subsidiary reconciliation, and cash flow tracking.
Unified Cost-Center Integrity
Integrated multi-departmental spending with the core financial books, resulting in zero variance between operational expense reports and system ledger values for the first time in company history.
Conglomerate-Wide Intelligence
Stakeholders now manage 5+ subsidiary companies from a single Command Center dashboard, providing real-time visibility into aggregated cash flow and project-wise ROI.
100% Audit Accuracy
Successfully passed two external audits with zero findings, thanks to the immutable double-entry engine and robust document versioning system (amending workflow).
